The Lowdown
Alright, Rusty here, switching to imperial for the crew that thinks in feet and miles.
The forecast starts a bit slow. Saturday the 5th has a tiny 2ft SSE swell, glassy in the morning – you might get a few knee-high lumps if you’re keen. Energy is weak at 126. Afternoon gets trashed by a cross-shore wind, so forget it.
Sunday the 6th and Monday the 7th are poor to marginal. Sunday is onshore and choppy, building to 7ft with a short 8-second period – messy. Monday morning is still light cross-onshore with a 7ft S swell. The real standout lands Monday afternoon, 7th September: glassy conditions, 8ft from the south, 10-second period, energy at 1170. That’s a punchy, clean south swell for experienced surfers only – absolutely the session to aim for.
Tuesday the 8th stays clean with a dropping 5ft S swell in the morning (energy 901). Wednesday the 9th morning has a tiny offshore breeze, 6ft east swell, but short 7-second period – a bit weak. Thursday the 10th morning is glassy, 4ft south swell at 12 seconds, energy 477, clean and lined up.
Friday the 11th looks very good: 4ft south groundswell at 14 seconds, energy 555 – long period lines, might be a bit straight but clean.
From Saturday the 12th, it fades. Sunday the 13th and Monday the 14th get messy with strong onshore winds and big swell – 10ft at 11 seconds Sunday afternoon, but straight onshore. Skip it.
Tuesday the 15th sees a massive 10ft SSE groundswell at 14 seconds, energy screaming at 3919 – but it’s too big for this break, even with clean winds. Only for the serious big-wave crew.
After that, a mix of onshore and clean. Wednesday the 16th is onshore, poor. Thursday the 17th morning drops to 5ft SSE at 13 seconds with clean offshore ENE wind – very good again.
The final highlight is Saturday the 19th afternoon: 4ft SSW at 11 seconds, energy 685, light cross-off – sweet. Sunday the 20th morning is offshore at 20 km/h with a 6ft SE swell at 8 seconds, energy 597 – bumpy but tidied by the wind.
Jaconé is an exposed beach break, consistent, intermediate level. Optimum swell direction is SE. Crowds are “sometimes” – you’ll have company on the good days, but nothing wild.
Best call: Monday afternoon the 7th – glassy, 8ft S swell. For the second week, Saturday the 19th afternoon is the safe bet.
Rusty out.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
